Then , based on lemons model , the paper analyses the market conductibility of the alteration of financing capital ' s use 然后,在阿克劳夫模型的基础上,对上市公司变更募集资金投向的市场传导效应进行了理论分析。

Al self - oxide powder , al2o3 - al blending powder and sic - al blending powder extrusion wires obtained by experiments had high tensile strength as well as high conductibility 实验所得的铝粉末自氧化挤压线材及用al _ 2o _ 3和sic颗粒强化所得的线材具有高的抗拉强度和良好的导电性能。

In the years of errors and corrections respectively , through the empirical analysis on stockjobbing amount and price , it researches there ' s no difference on studied sample and control sample in appointed areas , and the investors of our securities business have no specially attention on these information . on the other word , we validate the corrections of accounting errors have no market conductibility . later , it analysis the reasons 分别在会计差错的发生年度和差错的更正年度中,通过测试和控制样本的股票交易量、平均超额收益率和累计超额收益率在报表公布日前后各30天的时窗内的检验,说明我国证券市场的投资者对这类信息未予以特别关注,即我国上市公司的会计差错及其更正行为不具有市场传导效应,并进一步从理论上分析了这种现象产生的原因。

Based on the above , a surrogate models are built for thermal conductibility performance of sandwich panel with " v - type " folded core in this paper , and they can be optimized by multi - subject . the numerical simulation function and optimization design method in condition of lightest weight are shown in this paper 其次,用isight软件重新设计了40组不同构型的试验设计点,并以此为基础对v型褶皱芯材夹层板的热传导性能构建了可用的代理模型,给出了数值模拟函数和最轻重量条件下的优化设计方法。

In this dissertation , refining grains , depositing conductibility carbon film on the surface of the particles and doping mg ~ ( 2 + ) into the lattice of lifepo4 were adopted to improve the electro - chemical performance of the cathode material . the cathode material lifepo4 mainly has two flaws , the low conductibility and the slow li + ion diffusion , which have a bad influence on the performance of the cathode material 论文主要针对制约正极材料lifepo _ 4性能的两大致命的缺点,即低的电子导电率和低的锂离子扩散速率,采取材料颗粒的细化、颗粒表面沉积碳导电层以及mg ~ ( ~ ( 2 + ) )离子掺杂等措施对其进行改性探索,以提高正极材料lifepo _ 4的电化学性能。

This article takes the corrections of accounting errors as one of the profit - manipulate . it begins with the root and the objective condition of the profit - manipulate , to analysis the reason and motivation of the corrections of accounting errors . then , on the base of the effective market content and the capm theory , this paper analyses empirically the market conductibility of corrections of accounting errors with all " a " shares in 2001 , and discovers there is no difference on stockjobbing amount and price 从利润操纵存在的根源和客观条件入手,分析上市公司进行会计差错及其更正的原因和动机;然后,以有效市场假说的基本理论和资本资产定价模型为基础,对2001年沪市a股所有进行会计差错更正的上市公司进行会计差错的发生和更正的市场传导效应研究,通过检验发现,公司年度报告披露前后时窗内的股票交易量和股票价格并未存在显著差异。

6 5 = 27 . 8 % , o r = 74 . 3 % iacso the second , above alloys not only have good strength and conductibility at room temperature but also have good strength at high temperature . bar alloy can hold o b = 274mpa and o o2 = 250mpa at 350 ? while end ring alloy can hold o b = 200mpa and o 02 = l65mpa at350 ? 研究合金不仅在常温具有很好的强度和导电性,而且具有较高的高温强度,导条合金在350时b仍保持在274mpa左右, 0 . 2仍保持在250mpa左右;端环合金在350时b仍保持在200mpa以上, 0 . 2仍保持在165mpa以上。

The temperature of surface concrete varies with environmental temperature , but the conductibility of inner concrete is very poor . as a result , a quick decrease of environmental temperature will lead to large temperature gradient and then tensile stress develop soon in the thick direction , which will probably occur on the entire cross - section 混凝土表面温度随外界温度波动而波动,但内部的导温性能很差,所以在外界温度骤降时将引起很大的温度梯度,从而在厚度方向上拉应力发展很快,这极易引起全断面拉应力发生。
